IMPROVEMENT lN PLOWS.

Specification forming part of Letters Patent No. 23,904, dated May 10, 1859.

To all whom it may concern:

Be it known that I, EDWARD DAvI soN, of Batesville, in the county of Independence and State of Arkansas, have invented a new and useful Improvement in Flows, and I do hereby declare that the following is a full, clear, and exact description of the same, reference being bad to the annexed drawings, making a part of this specification, in which Figure 1 is a side sectional view of my invention, taken in the line 00 m, Fig. 2. Fig. 2 is an inverted plan of the same.

Similar letters of reference indicate corresponding parts in the two figures.

Various attempts have been made to con struct plows capable of being used either as an ordinary or a subsoil plow, but so far as I am aware they have proved failures, either on account of bcingtoo frail or light for the work required of them, or, if made sufficiently strong, too heavy and cumbersome for general use. By this invention I have overcome these difficulties and obtained a plow that will perform the desired work, be sufficiently light for ordinary use, and still sufficiently strong and durable.

To enable those skilled in the art to fully understand and construct my invention, I will proceed to describe it.

A represents the beam of the plow. B B are the handles, one of which, B, is attached to the inner end of the beam A and to the landside 0, and also to a plate, a, above the landside 0, the other handle, B, being attached to the mold-board D, the two handles being connected by cross-ties I). The beam A and handles B B are of usual construction. The handle B is attached to the beam A by a metal stirrup, o, the front edge of which is locked, as shown at d, to a metal bar, e, secured to the under side of the beam A.

To the front end of the bar 6 a metal rod,f, is attached by a bolt,g. This rod extends along under the beam A and around in front of its front end and over on its top, with a bolt, h, passing through it, the curve of the rod being perforated to form a clevis, as shown clearly in Fig. 1.

The plate a and mold-board D are attached to a standard, "6, the upper end of which passes through the bar 0 and beam A, and has a nut, j, on its upper end.

The landside O and its share E are connected at their front ends, and are attached to the lower end of the standard 6 by a shoe, is, which passes under a bar, 1, projecting laterally from the landside O, as shown clearly in Fig. 2.

F is a supplemental landside and G a supplemental share, the front ends of which are connected, and have the lower end of'a colter, H, attached to them. The share G is a blade of steel of proper width,'and is directly in front of share E, and the landside F is directly below and in the same plane with thelandside G. The upper end of the colter H passes through the bar a and beam, and is secured in proper po sition by a key, m.

To the inner side of the landside F a bar a is attached. This bar serves as a guide, and it passes through a guide-loop, I)", attached to the inner side of plate a. and the standard z, and is secured by a bolt, 0", to said plate.

From the above description it will be seen that the share G and landside F may be raised and lowered by adjusting the bar a and colter H higher or lower.

When the share G and landside F are in contact with the share E and landside (J the plow may be used as an ordinary plow for turning a furrow, but by depressing the share G and landside F the plow is converted into a subsoilplow.

The bar 6, rodf, and stirrup o strengthen the beam, and, in fact, the whole plow, and in conscqence of having the supplemental landside F, share G, and colter H connected together said parts are rendered strong and durable.

I do not claim, broadly and irrespective of construction and arrangement as herein shown and described, an adjustable share and landside; but

I do claim as new and desire to secure by Letters Patent The combination of the bar '6, stirrup 0, rod f with the adjustable supplemental landside F, share G, and the stationary share E and landside O, the whole being arranged substantially as described.

EDWARD DAVIDSON.
